Solution Overview
Problem
The challenge in modern semiconductor technology is to improve storage space utilization and memory reliability while managing the increasing integration density and performance of memory systems.
Innovation Solution
A memory controller with a buffer and processor is designed to generate identification codes for continuous logical addresses with the same data type, reducing storage space by labeling multiple data pieces with a single code, and transferring data efficiently during power-off scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each data piece is labeled with a separate identification code, then data type identification is accurate, but storage space is wasted
Solution Approach 1:
The patent merges multiple identification codes into a single code by detecting continuous logical addresses with the same data type. Instead of assigning separate identification codes to each data piece, the system combines them into one unified identification code that represents the entire continuous range, thereby reducing storage space while maintaining accurate data type identification.
Solution Approach 2:
The patent segments the storage space by identifying continuous ranges of logical addresses that share the same data type. By dividing the address space into continuous segments and assigning one identification code per segment rather than per individual address, the system reduces the total number of identification codes needed while preserving precise data type tracking.
2Productivity
If identification codes are stored in buffer during normal operation, then data transfer is efficient, but buffer space is consumed during power-off scenarios
Solution Approach 1:
The patent reduces buffer space consumption during power-off scenarios by merging multiple identification codes into a single code for continuous logical addresses. This consolidation means fewer identification codes need to be stored in the buffer during power-off, freeing up buffer space while maintaining the ability to efficiently transfer and identify data types during normal operation.
3Quantity of substance
If continuous logical addresses with same data type are detected and merged, then storage space utilization improves, but processing complexity increases
Solution Approach 1:
The patent applies preliminary action by detecting and marking continuous logical addresses with the same data type before the actual storage operation. The processor identifies continuous ranges in advance, assigns a single identification code to the entire range, and stores this consolidated code in the buffer. This preliminary detection and consolidation simplifies the overall processing by avoiding the need to handle individual addresses separately during storage operations.
